Being a long time driver in Thailand, I will NOT drive in Bangkok.
If I need to visit the city, I will park my car at Don Muang car park and take a taxi into the city.
Not only is there nightmarish traffic, finding a parking spot anywhere near to where you have to go is getting almost impossible.
It is just not worth all the stress and wasted time.
The 2023 INRIX Global Traffic Scorecard, has Bangkok ranked as the 3rd worst traffic in the entire world.
The average driver in Bangkok, Thailand spends an average of 160 hours per year in traffic. That is just crazy.
If you have to visit Bangkok and you own a car and are driving inbound, you may want to seriously considering parking outside of the city and finding another way in.
